Hey Bernd,
I Just happen to have the Holley 52mm unit
I had a Tony D(fastman) unit on prior( worked flawlessly)
The Holley is Fully polished and has pretty red butterfly's that say Holley
and it works with all the sensor flawlessly.
we were all set to do a dyno comparison and the original writer backed out
and sent all the test units back.
Mine works great and is one if not the prettiest T.B's available
Also you are right about the T.B. having to work with the sensors correctly
, the only trouble on the sensors has been with some of the early F&B units
to my knowledge , I did have a buddy with some problems but Bruce went out
of his way to make it work.
50mm lightly modded, 52mm there on up and blown ......bigger is better...!
